Theatre and Film share so much in common, yet in very crucial ways they're worlds apart. They both use actors, sets, costumes and lighting. They both rely on scripts and are viewed by theaters full of people. But translating a good play to the screen is actually rather challenging. Often the finished film will betray its origins as a play through its limited number of locations. You feel like there is no real world outside the set where this story is taking place. That's certainly not the case with this William Wyler adaptation. This film is alive! People come in and out, this character interacts with that character, etc. It feels like a fictional police precinct and we are but a fly on the wall. And like a real fly, we get to move all over the place and see everything from the best angles. People who say Wyler was a lesser director can go take a long walk off a short pier.
